@In Srlpuilc referrer tu in time icttcts uteni mit tubing gmt it ille' time.

e` it known that I, J. R. ADAMS, oi' the city, county., und Stute of New York, have invented a new and improved Coffee-Mill; and I do hereby declare that thefollowing is a full, clear; hud exact description thereof,

which will enable others skilled in thenrt to make and use the sume, referencebeng hsdlto the accompon-ying y drawing, forming port of this specification, in which- Figure 1 represents a side elevation oi' this invention.

Figure 2 is u plan or top view of the same.

Figure 3 is a horizontal section of the same, the plane of section being indicated by the line a: z,-g. 1.

Similar letters ot reference indicate like parts. y v g This invention relates-to u cofee-inill, the lid of which is hinged 'to an arm extending fromthe top of the shuft, to which the grinder isseeured, said lid being provided with o handle secured to its inn-er surface. in such af manner thct,when the lid is opened,'^it takes the place of' the crank, by which the grinderis lsletinl-motion,l und when the lid is closed, the whole'imill is brought in a compact iorm, which con easily be .packed or stored away in a small space. The body of vthe mill is mudo in the form of a double cone, and it is provided with n aperture near its bottom, through which the ground c oftee cun'bc discharged. Said opening is opened and closed by u ring, which swivels on the body of the mill, and which is provided with-an aperture, so that, when theaperture of the ring registers with the opening in the body of the mill,'the ground coifee: een be discharged, and

when the ring is turnedY to such u position th'ntnits aperture does not register with the opening inthe niill, the space containing the ground coiec is securely closed, und the semeis not liable to open spontaneously.

- A represents the body of my mill, which is made in,the.for1n oi' a double cone, es shown in iig. 1. 'The upper cone forms the hopper, und the inner surface of the lower conc forms 'the concave grinding-surface, which corresponds to the grinding-cone, so that, by turning seid cone, coffee or other articles placed into the hopper uro ground ithe ordinary manner.' Suid hopper is provided with u. lid, B,'wl1ich is'hinged to an arm, a, extending from the central shaft C, undA which is provided with a handle, b, secured in its inner surface, as clearly shown in iig. 1, wherethc lid is shown closed in black, und open in red outlines, 'und also in'g. 2,whcre the lid is shown open. -When the lid is open, it tultes the picco of' the crank, by nieun's of which motion is imparted to the grinder, and when the lid is'closed, the entire mill ussumes a compact form, convenient for pecking or storing l in a small compass, and 'all its parts are fully protected, und not liable to 'sustnin any injury, if it (the mill) is thrown about or roughly handled. v

The lower portion of the, body of the mill is cylindrical, and provided with unuperture, c, through which the ground coffee can be discharged. This aperture isA opened orl closed by -a ring, d, which swivels on the cylindrical 'part of the body of the mill, und which isl provided with a-n opening, e. When the opening registers with the aperture c, the ground coii'ee cnn be discharged, but when the ring is turned to such a positiozn that said opening does not register with the aperture c, the space containing the ground coli'ee' is securely closed, and

there is lno d'unger that the same will open spontaneously, A pin, f, projecting from the inner surfaceofthe` ring, and working in a slot, g, in the body of the mill, prevents the ringbeing turned any further than necessary either to open or close the uperture'e.l l

I This ini'll is exceedingly compnct'in its construction. It is conveniently handled, can be stored away in a' small space', und is very durable.

I claimcs new, und desire to secure by Letters Patent- The pivoted iid of the mill, attached by an arm to thegrinder-shuft, for the purpose of turning cone,Y as described.
